## Antenna downtilt angle calculator | Antenna tilt angle calculator

This page covers Antenna downtilt angle calculator or Antenna tilt angle calculator. The Antenna downtilt angle calculator calculates distance from tilt angle and tilt angle from horizon distance. It also mentions formula or equations used in these antenna tilt angle calculators.

Antenna downtilt angle calculator uses height (in feet) and distance (in miles).
1 mile = 1.60934Km , 1 Km = 0.6214 miles
1 feet = 0.3048 meters , 1 meter = 3.28 feet
1 mile = 5280 feet

### Antenna Downtilt Angle Calculator #1

Following calculator calculates antenna downtilt angle based on base antenna height, remote antenna height and distance between antennas.

Base Antenna Height, Hb (input1 in feet) :

Remote Antenna Height, Hr (input2 in feet) :

Distance between antennas, D (input3 in miles) :

Antenna Downtilt angle(output in Degrees) :

EXAMPLE of antenna downtilt angle calculator:
INPUTS:
Hb= 120 feet , Hr = 80 feet , Distance = 5.4 miles
OUTPUTS:
Antenna downtilt angle = 0.08038 Degree

### Antenna Downtilt Angle Calculator #2

Following calculator calculates distance between antennas based on base antenna height, remote antenna height and antenna downtilt angle.

Base Antenna Height, Hb (input1 in feet) :

Remote Antenna Height, Hr (input2 in feet) :

Antenna Downtilt angle, theta (input3 in degrees) :

Distance between antennas (output1 in feet) :
Distance between antennas (output2 in miles) :

EXAMPLE of antenna tilt angle calculator:
INPUTS:
Hb= 120 feet , Hr = 80 feet , theta = 1 degree
OUTPUTS:
Distance between antennas (in feet) = 2291.5
Distance between antennas (in miles) = 0.434
